Humans evolved in partially isolated populations scattered across Africa
The textbook narrative of human evolution casts Homo sapiens as evolving from a single ancestral population in one region of Africa around 300,000 years ago. However, in a commentary published July 11 in the journal Trends in Ecology & Evolution, an interdisciplinary group of researchers concludes that early humans comprised a subdivided, shifting, pan-African meta-population with physical and cultural diversity. This framework better explains existing genetic, fossil, and cultural patterns and clarifies our shared ancestry.
